Jackson Bottom birds: February 19-25, 2010

Common GoldeneyeCommon Goldeneye, Jackson Bottom Wetlands, Hillsboro, Oregon on 17 February 2010 by Greg Gillson.


The rather rare COMMON GOLDENEYE and NORTHERN SHRIKE remained from last week. The GREAT HORNED OWL is still sitting on eggs. The BALD EAGLES have been adding material to their nest, but aren't incubating eggs yet.

An anonymous observer spotted a WESTERN SCREECH-OWL in a nest box, but exactly which of the dozens of nest boxes on the Preserve wasn't specified, and I couldn't find it--drat! A single early RUFOUS HUMMINGBIRD was spotted on February 20. TREE SWALLOWS arrived in small numbers during the week. An out-of-season BARN SWALLOW was seen February 26.

The patagial-marked RED-TAILED HAWK was here last week, but was reported this week by the Hillsboro Library staff at Dawson Creek Corporate Park. But, then, it was seen back here at Jackson Bottom on Friday again.

I am going to be leading free bird walks on the Preserve. The current plan is for these to be Wednesday mornings (nearly) every week, 8:30-11:00. Bring your boots for muddy trails. Be prepared to walk leisurely up to 3 miles (you can drop out at any time) as we visit ponds, woods, riparian, and upland grassland areas for a general census of all birds present. Participation is limited, so please email me, Greg Gillson to make sure space is available.
